Cognitive Work Analysis to Support Collaboration in Teamwork Environments
MetadataShow full item record
Cognitive Work analysis (CWA) as an analytical approach for examining complex socio-technical systems has shown success in modeling the work of single operators. The CWA approach allows room for social and team interactions, but a more explicit analysis of team aspects can reveal more information for systems design. CWA techniques and models do not yet provide sufficient guidance on identifying shared constraints, team strategies, or social competencies of team players. In this thesis, I explore whether a team approach to CWA can yield more information than a typical CWA. Team CWA techniques and models emerge and extend from theories and models of teamwork, past attempts to model teams with CWA, and the results of two sets of observational studies. The potential benefits of using Team CWA models in domains with strong team collaboration are demonstrated through the results of a two-week observation at the Labour and Delivery Department of The Ottawa Hospital and a fifteen-week observation at the IBM Ottawa Software Group.
